Answer 1

Answer is 60.

Explanation:

Two equations, two unknowns.

As you said, let x be the number of $5 items and y the number of $25 items.

First equation is based on VALUE (second sentence):

5x + 25y = 1950

Second equation is based on NUMBER (third sentence):

x + y = 150

Now solve. Easy way is rearrange the second equation (x = 150 - y) and sub into the first:

5(150 - y) + 25y = 1950

750 - 5y + 25y = 1950

20y = 1200

y = 60

Since y represented the number of items sold at $25, 60 is the number of items.
